Isolated Nerve Palsy of the Flexor Pollicis Longus After a Radial Shaft Fracture: A Case Report

We present the case of a patient who developed an isolated palsy of the flexor pollicis longus (FPL) branch of the anterior interosseous nerve (AIN) following a fracture of the right radial shaft. The diagnosis of AIN palsy in this setting is rare, especially involving partial neuropathies of only t...

Description
Summary:We present the case of a patient who developed an isolated palsy of the flexor pollicis longus (FPL) branch of the anterior interosseous nerve (AIN) following a fracture of the right radial shaft. The diagnosis of AIN palsy in this setting is rare, especially involving partial neuropathies of only the FPL branch. Clinical presentation in this scenario can be mistaken for other musculoskeletal pathology, and electrodiagnostic studies can be helpful in confirming the diagnosis.
